摘　　要：采用透明圈等方法,结合酯化能力、耐酒能力、耐酸能力试验,最后筛选出SGAS2004.0001和SGAS2004.0002两株酯化菌,并将SGAS2004.0001用于酿酒生产和制曲生产。结果表明,所产基础酒的己酸乙酯含量平均提高了25～35 mg/100 mL;用SGAS2004.0001菌株制成的麸曲用于双轮底、多轮底酒生产,能使双轮底、多轮底调味酒的己酸乙酯含量提高40～65 mg/100 mL,而且产酒的口味更加醇厚、幽雅,窖香更浓,味更长。Two esterifying bacteria strains including SGAS2004.0001 and SGAS2004.0002 were obtained by transparent circle method coupled with the test of esterifying capability, alcohol resistant capability, and acid resistant capability. In addition, SGAS2004.0001 was used in liquor-making and starter-making experiments. The results suggested as follows： ethyl caproate content in produced base liquor increased by 25 -35 rag/100 mL in average, and the use of bran starter （produced by SGAS2004.0001） in the production of liquor by double bottom fermentation or by multiple bottom fermentation could increase ethyl caproate content by 40 -65 mg/100 mL in blending liquor and the produced liquor had better taste with elegant pits flavor.
